.What is the KE of a baseball that has a mass of 100 kg and is traveling at 5 m/s?
Elden [556K]

Answer:

1250joules

Explanation:

The kinetic energy is energy in motion and it's formula is

KE =1/2MV^2

M represent mass which is 100Kg.

V represent velocity which is 5m/s

Therefore, KE = 1/2×100×5× 5

= 50 × 25

KE= 1250joules

How are compounds created?
Flauer [41]

The answer is that compounds are formed when elements are joined and held together by strong forces called chemical bonds.Covalent bonds share electrons between atoms in order to fill their electron shells. In the compound, molecules are held together by the attraction between the nucleus and the shared electrons. (I got this from the internet so credits to the internet)

In the gaseous state, chlorine exists as a diatomic molecule Cl2 (Molar mass = 70.9 g/mol). Calculate the number of moles of chl
kap26 [50]

Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond

molar mass of the diatomic molecule is 70.9 g/mol

therefore 70.9 g of Cl₂ is - 1 mol

then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol

there are 1.97 mol of Cl₂ present
